Carlos Alcaraz responds to Novak Djokovic "spying" controversy

Carlos Alcaraz addressed claims accusing his father of recording Novak Djokovic's practice sessions

Carlos Alcaraz entered a spying controversy after he wrapped his Center Court performance and booked a spot in the grass-court Major's semifinal.

Following his victory, the Spaniard had to deal with reports claiming his father Carlos was accused of recording the No. 2 seed Novak Djokovic's practice sessions at the All-England Club's Aorangi Park in hopes of taking undue advantage ahead of their potential final clash at the Championship.

The World No.1 defended his father's actions after he admitted that the incident was "probably true" as he is an avid tennis fan who most likely relished the training of a legend like Novak Djokovic.

"Oh, probably it is true. My father is a huge fan of tennis. He doesn't only watch my matches. I think he get into the club at 11 a.m., get out at 10 p.m., watching matches, watching practice from everyone. Be able to watch Djokovic in real life, yeah, probably it is true he's film the sessions," Alcaraz said.
